Night of the Living Dead (1968)

When radiation raises the dead, a diverse group of people take refuge in a deserted farmhouse. The situation is complicated by the fact that those who are slain by zombies, later come back to life as zombies. A classic horror film laced with commentary on the state of American society in the late 1960s. Essential viewing for any Horror fan.

Trivia: Made for $100,000, by 1979 the film had grossed over $12 million worldwide.
